U of Sask student, epidemiologist team up to track Canada's rapid test results, fill COVID-19 data gaps

An online tool made by a University of Saskatchewan student could offer a clearer picture of how COVID-19 is spreading in Canada, by tracking results from rapid tests across the country.

Last month,the Saskatchewan governmentjoined some other provinces in encouraging residents to use rapid antigen tests, which can be taken at home, instead of seeking outa PCR test,unless their symptoms are severe.

The PCR, or polymerase chain reaction, tests given at provincial testing sites are considered more accurate, butthe province has said the shift to relying on rapid tests was neededto help preserve PCR testing capacity for high-risk populations.

However, that's left gaps in the official data, according to U of S epidemiologist Nazeem Muhajarine.

Only cases confirmed through PCR tests are included in the official COVID-19 numbers reported by the province.

But Muhajarine estimates that for every positive PCR test, there are two positive rapid test results that go unreported.

"It compromises the understanding of the COVID-19 disease distribution in our province and in our country, so I think that it's a huge issue," Muhajarinesaid.

Sohe reached out to Noah Little, a biomedical neuroscience student at the U of S who created an online COVID-19 tracker.

The website already records cases and vaccine rates across Canada and now, it's tracking rapid test results as well.

Little's new tracker allows people to anonymously report their positive rapid test results by enteringtheir postal code, age and the day they took the test.

"What this does is it adds it to a database of rapid test results that can be used for research and can be used to better understand these gaps in data," he said.

Little said he's been interested in adding the rapid test results to his site since noticing other jurisdictions were pointing people to the at-home rapid tests over PCR tests.

He added that it only took about a day after Muhajarine reached out last week before he got the first prototype up online.

Little says since then, roughly 1,000 people a day have submitted their rapid test results through the siteboth positive and negative, which helps to monitor test positivity rates.

"The more people who are able to submit to this, the more completepicture we'll get of the [COVID-19] spread in Canada," he said.

Little said the statistics are currently being plugged into spreadsheets. By next week, he plans to turn those numbers into an online dashboard similar to how he's helpedpeople visualize the official caseand hospitalization data.
